⛽️ Costco-Branded Credit Card Holders Get 5% Back on Costco Gas

Costco members who enjoy using the Costco-branded credit card for gas at store locations are now getting an even better deal.

The credit card offers 5% cash back at Costco gas pumps. All other eligible gas purchases and EV charging purchases earn 4% cash back.

We noted the 5% reward level in our most recent review of the branded credit card in July. But other media outlets are framing the reward as a quiet new change. So you may see headlines about it and wonder.

These cash back rates only apply to the first $7,000 in annual gas purchases. Once you’ve hit the annual limit, the cash back figure drops to 1%.

If you purchase all your gas at Costco with your card, you’ll get an additional $70, bringing your total cash back to $350 instead of $280.

The credit card renewal rate hovers around 90% annually thanks to perks like this.

You still get 3% cash back on restaurants and eligible travel, 2% on purchases at Costco and 1% on everything else.
